Abstract

An experiment tested the null hypothesis that previous cropping and establishment methods would alter the mineral concentration of whole-plant spring wheat (WPSW) (Triticum aestivum). Four replicate plots (12 x 7.5m) of perennial ryegrass (Lolium perenne), chicory (Ch) (Cichorium intybus), red clover (RC) (Trifolium pratense) and white clover (WC) (Trifolium repens) forages were established as pure swards in June 2009 in a randomised block design. Forages were harvested 5 times per annum during 2010-2012 and forage removed. Forages were sprayed using a non-selective herbicide before each plot was split and spring wheat was sown in April 2013 either after ploughing or by direct drilling. Whole-plant spring wheat was sampled on 18th June for chemical analysis. Results showed previous cropping affected WPSW P, Mn and Cu concentrations. Lower N, P, K, S and Cu concentrations were found in WPSW after ploughing when compared with direct drilling. Within direct drilled plots, WPSW following RC had higher Ca concentrations compared to other previous forage treatments. Within ploughed plots, WPSW following RC had a lower Mg concentration than Ch and WC. Overall, findings showed previous crop and establishment method alter mineral composition of WPSW but results varied for each mineral.
